A smooth pipe with a diameter of 2.0 cm is maintained at a constant wall temperature of 90°C. Water enters the tube at 40°C and leaves at 60°C. If the entering velocity is 3 m/s, calculate the length of tube necessary to accomplish the heating. The empirical relation proposed by Petukhov for fully developed turbulent flow in smooth tubes may be used: (16) Reqpr (0.5 S Pr s 2000, Nud = 10+ < Reg < 5 x 106) 1.07 + 12.7 (4)? (Pr} – 1) and friction factor obtained from the following relation for smooth pipes: f = 0.184 Re-0.2 (2 x 104 < Re <3 x 105) =
